I have a Canon TR8520, which runs off Apple/iMac computers, and I cannot get it to stop printing two-sided documents when printing from Adobe Acrobat. I have no trouble with other applications, e.g., Word, but my .pdf files always print two-sided.
I do not have two-sided checked in the Printer preferences.
Any thoughts appreciated!
There are several places 2 sided or duplex printing can be enabled. I would suggest posting in the Adobe forums, as this might get you a work around or solution faster than posting here. But if you want help, you'll need to share more information about your environment like your OS version, Version of Acrobat, etc.
